There almost certainly is something causing a conflict. Hooking issues with multiple games almost always are conflicts with other software (or integrated/dedicated GPU issues on laptops).
Did you try the alternative hooking method and installing hook helpers? The latter should help with most conflicts without getting to the bottom of the matter by ensuring that vorpX gets loaded as early as possible. The ‘Attaching to …’ dialog offers the option to switch to alternative hooking or install a hook helper after about a minute of waiting or so.
If you tried to launch games from the desktop viewer, please also try directly from the Windows desktop without the vorpX desktop viewer. Should be no problem normally, but just in case.
